Lennox SPA048H4 Ignition Control Board
The purpose of the ignition control board is that it has control over the gas valve, the ignition timing and some more sensing equipment. It is an important device that is now usually a major component of the main board for enhanced safety.
What are some indications that my ignition board is on its last leg?
- Ignition sequence fails to begin when called upon
- Any other problem connected to the system checks out flawless
- The electrical signal from the home thermostat never gets to the Lennox control board
